Temperature Adjustment Factors

In general, if the operating temperature of a metal hose assembly increases, the Maximum Allowable Working Pressure (MAWP) of the assembly decreases. Elevated service temperatures will decrease these pressure ratings by the factors shown in the following chart for the alloy used in the braid wire.

Temperature Adjustment Factor Based on Braid Alloy

The Calculator below will help you to find MAWP of a certain product at a given elevated temperature.

To use Calculator please follow these steps:

  • Choose a Hose Series to calculate MAWP for
  • Select specific product within that series
  • Enter temperature in the application [AT] and click “Calculate” button
  • See respectively adjusted MAWP for a single braided (1X-braid) or double-braided (2X-braid) hose

Note: The temperature adjustment factors used in calculations are based on Braid Alloy – for Hose Series P3, 600, 700, 800 and 900 assumed to be 304/304L alloy; for Series 740 Monel 400 alloy; for Series 794 phosphorus bronze alloy.
